Abstract: In this paper we discussed about an optimum design of Dielectric Resonator Antenna (DRA) for wireless Applications with single feed structure has been designed and investigated in this paper. Proposed antenna radiates at 4th band Resonating frequencies are 2.38GHz, 3.56GHz, 4.59GHz and 8.26GHz and gain of the Antenna are respectively 6.42,5.65,6.7, and 5.9 respectively which is widely used for the Wireless applications. The 10dB fractional Bandwidth of the Antennas are 10%, 5%, 3.7% and 11%. A micro-strip feed line is used to excite the antenna; length of slot is used for impedance matching. From the return loss plot it is verified that it is Multiband Antenna.
Keywords: Hemisphere, DRA, Cross-Slot, Coax Feed, Length of Slot.
Scope of the Article: Microwave Antenna
